Replaced iPhone4 battery. Now randomly restarts and battery % broken!
My wife's iPhone4 (AT&T) battery was draining very quickly so we bought a replacement through iFixIt.com. I followed the steps exactly, and thought I had performed the upgrade perfectly. Now we are running into issues.
First off, the battery % indicator doesn't seem to increase when on the charger. For example, my wife had 55% battery power when she went to sleep and put the phone on the charger. When she woke up, still 55%. She restarted the phone, which then dropped the battery level to 22% (even though it had been on the charger all night).
Now the phone is randomly restarting by going black, then immediately to the startup screen (white Apple logo). It restarts very often.
Obviously something is very wrong. Could it be that the battery we received was a lemon? I had no trouble with the installation. The phone does make and receive calls, when it's not randomly restarting.
I reinstalled the old "quick to drain" battery, and the problems stopped. The phone no longer randomly restarts, and the battery indicator level (%) does increase while being charged. It's looking like the new battery itself is the issue.
Please help! My wife can't live without her iPhone.
the new battery is not the original one . i already faced this problem . i have changed the battery on iphone4 with the cheap market. after installing battery phone not charging the battery as same as remained charged. battery percentage is not increasing . but after changing the battery again with the original problem solved. the original battery i pulled form working phone. just change the battery. it will solve your also problem.
Before you go and start huffing and puffing about the bad batteries make sure you have some settings disabled first! :P
WiFi - This is the No.1 cause of minimal battery life. A lot of people leave this bad boy on when they aren't even using it, or they don't even realise it is on in the first place. The common mistake people make with this is they presume the WiFi is off when it says
That purely means it is not connected to a wifi router, it does not mean it is physically turned OFF. It still in fact runs at full battery draining capacity because it is constantly searching for new/old networks to connect to.
To solve this issue, make sure this setting is switched to
NOTE - After you update/restore your iPhone, the default factory settings are enabled and good old WiFi is enabled again. Also try to only use WiFi where there are power supplies to recharge your iPhone with.
Bluetooth - Make sure this sucker is disabled as well. Unless you are in your car using it for handsfree or at home using it for music, KEEP IT OFF.

Wow, it's like MY husband wrote this about me... I installed a new battery today because my iPhone 4 is now a year old and only holds a charge for 4-6 hours and so I am charging twice a day. (and yes, I always turn off my wifi when not using it). I completed the installation successfully and charged it for 9 hours. Then, when I went to turn it on, it said "activation required" and forced me to connect to iTunes. Then, it started on an endless loop rebooting and wouldn't work... Very frustrating! My husband ended up putting the old battery back in for me because I was freaking out (I too cannot live without my iPhone). I guess no one here as the REAL answer for us... Just cheapo lemon battery replacements I guess.
New replacement for GSM and CDMA iPhones. — 50+ available at 24.95 each.
have a similar problem with my iphone battery. The battery connector broke off a couple of days ago.. I soldered it back on it but now the problem is:
when I connect the device there is always the jack symbol (insteat of the flash)
the percentage doesn´t move..only when I restart the device..
but I noticed that the battery is charging... because when I reboot the device after loading the battery for some hours the percentage raises to 100%...
but it stays there the whole day until I reboot the device..
so actually the problem is that it doesn´t refresh..
Any suggestion or idea for me??
I had no charging and no wifi with the replacement battery from ifixit. After two evenings of troubleshooting I put the old one back in and everything was fine.
Ifixit has a batch of batteries I would say judging by the number of people with issues right after battery replacement.
Hoping the second replacement will actually work.
